** Even if purchased in units of 10 (1 box), they will not be delivered in a single box.
* Terminal types and tightening angles may vary by vehicle model. Please refer to the links for detailed compatibility and installation instructions..

* The image is only for reference. The image shown may differ from the actual product.

Provides stable ignition performance and combustion efficiency at an affordable price, bringing out the engine's true potential.

Features of Resistor Plugs:
Built-in ceramic resistor to suppress ignition noise generated during sparking.
- Suppresses ignition noise to prevent interference with car radios, mobile ham radios, and car phones.
- Prevents malfunctions in engine control computers caused by noise.

* Effects may vary depending on the vehicle.

About Plug Terminal Shapes:
Please select the terminal shape that matches your engine and plug cord. Terminal shapes include "Integrated," "Separated," "Threaded," and "Punch-riveted."
- Four-wheeled vehicles typically use "Integrated" or "Punch-riveted" types.
- Two-wheeled vehicles typically use "Threaded" types.
- Plugs used for both may have a "Separated" configuration.
- The "Separated" terminal can be removed, but "Integrated" and "Punch-riveted" terminals cannot. Attempting to force them off may break the terminal.
- When using a "Separated" type as a "Threaded" type, remove the terminal nut. If using with the terminal nut attached, ensure it is tight; if loose, tighten gently with pliers.

Features of NGK Plugs:
- Ultra "Wide Range" Plug:
The center electrode features a "copper core" structure that seals copper near the tip to dissipate large amounts of heat quickly, resulting in a wide heat range resistant to both overheating and fouling.
- High-Alumina Ceramic Insulator:
Excellent insulation at high temperatures for reliable sparking, superior thermal conductivity to prevent overheating, and high resistance to thermal shock and mechanical stress.
- Robust and Airtight Construction:
The insulator and metal shell are joined with special powder for excellent airtightness and structural durability.
- Superior Durability:
Uses special nickel alloy electrodes for long-lasting performance.
- Insulator Corrugations:
Prevents flashover by increasing the surface distance between the terminal and the metal shell to ensure insulation.

Stable NGK
Stable Plug Exchange
more regularly than Windshield IRIDIUM.
Replacement with same part number as OEM
An unmistakable gem
A reliable part that does its job well
Regular replacement of Standard Plug BP 5 HA is effective.

I am in the process of refreshing the entire used car with 40000 km of unknown maintenance history, but it was beautifully dead. I was impressed that the engine was running so well, but the engine was not difficult to start and was running normally, so I thought it was NGK. After replacing the engine with the new one, the fuel consumption slightly improved and the engine started to blow up better. 40000kmPlug seems to have been without replacement. Recently, Windshield IRIDIUM, MotoDXPlug, etc. have come out, but I don't think I can feel the price/effectiveness, and it is impossible for me to feel 2.3% increase in fuel efficiency, although it is written in the homepage. It may look like there is a difference on the GraphMagic, but in reality, the difference is only 0.2 seconds, so be careful not to be fooled by the GraphMagic. The price is high, and I think a normal plug is sufficient. Just replacing a regular plug that has deteriorated will make a considerable difference. I have heard that Windshield IRIDIUM is good for high-revving engines, and I would like to replace it with a higher grade plug such as MotoDX or Windshield IRIDIUM. I want one so bad lol.

Cospa is good

Standard Type is sufficient as it is replaced regularly.
I used to use the expensive Plug but I can't tell the difference in blowing up. I think this one is better in terms of cost-effectiveness.

If you have a plug wrench, you can replace it easily.

The Plug itself is a very good product because it is easy to replace as long as you have a Plug wrench.

Amazon's $500 stock won't be revived, so I'm requisitioning it for maintenance in December.
I think the difference is about 1 pc of Plug.
I'd be happy to combine OEM air cleaners and other products for free shipping.
